In the global electronic component industry landscape, TDK Corporation has become a core force driving the development of an intelligent society with its profound materials science heritage and comprehensive product layout. Founded in 1935 and headquartered in Tokyo, Japan, TDK has always focused on the commercial application of key electronic materials such as ferrite. Today, it has built a diversified product matrix covering passive components, sensor systems, magnetic application products, energy application products and other fields, and owns several well-known brands including TDK, EPCOS, and InvenSense. Relying on its global design, manufacturing and sales network, TDK products are widely used in cutting-edge fields such as automotive electronics, industrial control, consumer electronics, and information and communications. Its FY2025 sales reached 14.4 billion US dollars, with more than 105,000 employees worldwide, establishing a dual benchmark of technology and quality in the electronic component industry.
As an important part of TDK's core competitiveness, the sensor and passive component series have become core configurations for many high-end electronic devices due to their excellent performance and reliability. Below, combined with all designated models under TDK such as ICM-42688-P and MPU-9250, we will analyze their functions and application values by product category.
Motion sensors are one of TDK's advantageous product lines, covering various specifications of Inertial Measurement Units (IMU) such as 6-axis and 9-axis, integrating core components such as gyroscopes, accelerometers, and magnetometers, and are widely used in fields such as consumer electronics, automobiles, and industrial robots. Among them, 9-axis motion tracking sensors are characterized by high integration and low power consumption, with typical representatives such as MPU-9250 and ICM-20948. The MPU-9250 is the world's smallest 9-axis motion tracking device, adopting a 3×3×1mm QFN package, integrating the MPU-6500 (3-axis gyroscope + 3-axis accelerometer) and the AK8963 3-axis digital compass. Its power consumption is only 9.3μA, and its gyro noise performance is 3 times higher than that of competitors, making it suitable for consumer scenarios such as smartphones, wearable devices, and 3D remote controls; the ICM-20948 features "the world's lowest power consumption", also integrating a 9-axis sensor and a Digital Motion Processor (DMP), supporting I²C and high-speed SPI communication, which can reduce the load on the host processor and perfectly adapt to the low-power requirements of IoT and wearable devices.
The 6-axis motion sensor series further enriches application scenarios, covering full-dimensional needs from consumer-grade to industrial-grade and automotive-grade. Star products in the consumer electronics field include ICM-42688 and ICM-42688-P. The former, as a high-precision 6-axis sensor, has been applied to the recording anti-shake function of smart glasses, while the latter inherits high-precision characteristics and is suitable for scenarios such as AR glasses and game controllers; relying on ultra-low power consumption advantages, the ICM-42670-P achieves the industry's lowest power consumption in 6-axis working mode, with a package size of only 2.5×3×0.76mm, making it an ideal choice for miniaturized products such as wearable devices and hearables. In automotive-grade products, the IAM-20680HT and IAM-20685 perform outstandingly. The IAM-20680HT can work in a wide temperature range of -40℃ to 105℃, supporting non-safety automotive applications such as vehicle dead reckoning and telematics, and can achieve precise positioning even in scenarios where GPS signals are missing, such as tunnels and multi-storey parking lots; the IAM-20685 focuses on the ADAS and autonomous driving fields, providing core support for high-precision positioning and image stabilization. In industrial and IoT fields, the ICM-45686 is suitable for scenarios such as AR/VR controllers and industrial robots due to its dual-interface design and low-noise characteristics; the IIM-42652 (corresponding model 11M-42652), as an industrial-grade 6-axis sensor, has a 20000g anti-shock capability, supports multiple interfaces such as I3C, I2C, and SPI, and provides reliable guarantee for industrial applications such as navigation and positioning, and platform stabilization.
Other models in this category also have their own specialties: MPU-6500 (including MPU6500), MPU-6050 (including MPU6050), and MPU-6000, as classic 6-axis sensors, provide basic motion perception functions for early consumer electronic devices; ICM-20602, ICM-20689, ICM-20600, ICM-20608-G, etc., focus on consumer-grade precise motion tracking and are suitable for devices such as smartphones and tablets; ICM-42605, ICM-42631, ICM-42607-P, ICM-42607-C (including lcm-42607) cover niche scenarios such as wearables and TWS earphones, among which the ICM-42607-C has been applied to the attitude motion detection of TWS earphones; ICM-40607, ICM-40608, and iam-20680 (corresponding to IAM-20680), as cost-effective 6-axis products, improve the layout of the mid-to-low-end market.
The audio sensor series under TDK's InvenSense brand provides core sound pickup solutions for audio devices with high sensitivity and low noise characteristics. The ICS-43434, ICS-41350, and ICS-41351 involved this time are all high-performance MEMS microphones, with a wide frequency response range and excellent anti-interference capability, and are widely used in devices such as smartphones, TWS earphones, and smart speakers. These models can achieve functions such as high-definition calls, voice assistant wake-up, and noise reduction by accurately capturing sound signals and cooperating with audio processing algorithms, bringing users an immersive audio experience.
Filters and inductors are core products of TDK's passive components, undertaking the key roles of noise suppression and stable power supply, covering power supply and signal processing scenarios in multiple fields such as consumer electronics, automotive, and industrial. Among the filter series, the ACT series common-mode filters perform outstandingly. ACT45B-510-2P-TL003, ACT45B-101-2P-TL003, and ACT1210-510-2P-TL00 all comply with AEC-Q200 automotive certification, can work in a wide temperature range of -40℃ to 150℃, and are suitable for noise suppression of automotive signal lines such as CAN-BUS and modems; ACM1211-102-2PL-TL0 and ACM70V-701-2PL-TL00, as general-purpose common-mode filters, provide noise protection for power lines of consumer electronics and industrial equipment; ZJYS51R5-2PT-01, as a common-mode inductor with a rated current of 2A, is suitable for EMC protection of various electronic devices.
The inductor series is represented by the SPM series. SPM4030T-R40M and SPM4030T-1ROM adopt metal magnetic materials, have the characteristics of large current and low DC resistance, and are suitable for power modules of devices such as laptops and servers; SPM6550T-4R7M, as a high-power inductor with an inductance value of 4.7μH and a rated current of up to 7A, provides stable energy storage and filtering functions for high-power power modules. In addition, LCP-20100 (speculated to be a model related to ICP-20100), as a high-precision barometric pressure sensor, can achieve 5cm-level height difference measurement, is suitable for scenarios such as smartphone 3D positioning and UAV altitude hold flight, has passed NextNav certification, and its performance has reached the industry-leading level.
